Anthracnose
scouted Sept. 16, 2021
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Union county, variety P55R49, were scouted and observed 5% of the field was affected by bleaching and browning between the veins and in the leaves, in localized patches.
- Conclusion
- The cause of disease was identified as Anthracnose, caused by Colletotrichum. While usually a disease that shows in the stems and the petioles, it can also cause leaf curling and reddening of the veins. Warm, wet weather favors infection and disease development. Crop rotation and tillage can reduce inoculum, while foliar fungicides will reduce disease, but it's usually not profitable.
